DiagnosisDiagnosis: Assigned to the genus Uroplatus and within the genus to the U. fimbriatus group based on molecular phylogenetic relationships and typical general appearance: a large Malagasy gecko with flat tail and lateral dermal fringes along head and body. It differs from U. fimbriatus and U. giganteus by smaller body size (SVL of adults < 140 mm vs. ≥ 150 mm) and a different iris colouration without a pattern of vertical lines. It can be distinguished from most populations of U. sikorae, including the ones from northern Madagascar, by absence of black colour on the oral mucosa (vs. presence), from U. sameiti by a larger number of supralabials (45–53 vs. 37–44, according to counts reported herein; Table 1), and from both these species by habitat (dry or transitional forest vs. humid rainforest). The new species is most similar to, and phylogenetically the sister species of, U. henkeli (Figs 7–9), from which it differs mainly by smaller adult body size (SVL 83–139 mm vs. 138–186 mm), a smaller relative tail width (TaW/SVL 0.12– 0.19 vs. 0.19–0.23), an unpigmented tip of the tongue (vs. black tip in U. henkeli), more extended yellow-reddish colour in the iris of most individuals, and apical serrated rotulae (vs. symmetrical fleshy apical structures with serrated elements) on hemipenes. Furthermore, the new species is genetically highly distinct from all other Uroplatus in the mitochondrial and nuclear-encoded genes studied, with numerous diagnostic substitutions in all pairwise comparisons and > 8% pairwise distance in the 16S gene fragment. The karyotype of the new species, based on a specimen from Montagne d’Ambre genotyped using a 16S sequence, was 2n = 36, with loci of NORs in a peritelomeric position on the 6th chromosome pair (Mezzasalma et al. 2022). (Glaw et al. 2023) 
Comment 
EtymologyThe species epithet is a Malagasy term containing the Malagasy word maso (= eye) and is used in Madagascar to refer to someone with bright, shiny eyes. The name refers to the often characteristic eye colouration of the new species, and is used as a noun in apposition to the genus name.
